How RYLAZE is given

Two dosing options: Monday, Wednesday, Friday or every 48 hours

After an allergic reaction to asparaginase derived from E. coli, the doctor may switch to RYLAZE. RYLAZE is administered through an injection into the muscle.

The doctor will choose 1 of 2 possible dosing options for RYLAZE. One option involves receiving the injection 3 times a week over the course of approximately 2 or 3 weeks on Monday, Wednesday, and Friday. Another option involves receiving the injection approximately every 48 hours over the course of 2 or 3 weeks.

Before treatment, the doctor will monitor and examine the patient’s health. 

Before administering RYLAZE, the doctor may first administer other medications to decrease the risk and severity of an allergic reaction, in case one occurs.

On the day RYLAZE is given, the doctor will determine the individualized dose and monitor for any negative reactions. If an allergic or adverse reaction occurs, alert the healthcare team immediately and treatment with RYLAZE should be paused or stopped.

Work with the healthcare team to understand what the treatment schedule means.

What is RYLAZE?

RYLAZE is a prescription medicine, given by intramuscular injection, that is part of a chemotherapy regimen used to treat adults and children 1 month or older who have acute lymphoblastic leukemia (ALL), a type of blood cancer that affects the white blood cells that help fight infection, and lymphoblastic lymphoma (LBL), a type of non-Hodgkin lymphoma that also affects white blood cells. RYLAZE is used in patients who have had an allergic reaction to E. coli asparaginase.

  • Blood clots (may be experienced as headache, arm or leg swelling, shortness of breath, or chest pain), which may be life-threatening
  • Bleeding, which may be life-threatening
  • Liver problems (may result in abnormal laboratory values) or, in severe cases, hepatic veno-occlusive disease (reduced blood flow in the liver)
